Metrohm has come up with a fully automated solution for determining Total Acid Number (TAN) and Total Base Number (TBN) in up to 112 samples.
The solution is based on the OMNIS Sample Robot, and addresses the needs of QC laboratories in the petrochemical industry as well as contract labs looking for a solution for high sample loads at the lowest possible cost per sample.
On the OMNIS Sample Robot, the entire analysis is performed in a closed system, so there is no risk of physical contact with solvents or reagents at any time.
For reliable and reproducible results, the sensor of the system is rinsed and conditioned after each determination. For increased safety and convenience, the system can be operated in any standard size fume hood.
The OMNIS Sample Robot can be expanded in three steps from size S to M to L, which accommodates up to 112 samples evenly distributed over seven racks. Racks with urgent samples can be prioritised and placed on the Sample Robot while the system keeps analysing.
Maximum throughput on the OMNIS Sample Robot is achieved using the possibility to perform up to four titrations in parallel at four works stations, saving up to 60 per cent in time compared to titration at a single work station.
